<p>The bottled consuming water enterprise has grown rapidly to diverse provinces and cities in the course of Indonesia now. The development of this enterprise is because of high call for clients and the lower nice of uncooked water in springs and wells PT. Cahaya Bumi Intanpari (CBI) is a agency that produces gallons, bottles, and glasses bottled drinking water beneath the logo “AirMu”. sales of bottled water every month constantly vary, the control of PT. Cahaya Bumi Intanpari calls for an estimate of the quantity of manufacturing of each type of bottled water to marketplace demand within the destiny. based totally at the description of the history, in this take a look at, a computing device-based application became designed and built. The research method used consists of information series and statistics analysis, statistics series includes remark, interviews, and literature have a look at, whilst statistics evaluation consists of making facts waft diagrams. The forecasting version is used in forecasting the income of bottled drinking water at PT. Cahaya Bumi Intanpari is a time series or it may be referred to as a time collection, and the forecasting technique used is unmarried exponential smoothing. From the outcomes of calculation checking out, it's far demonstrated that the single exponential smoothing method can be applied inside the AMDK income forecasting system, primarily based on the validity take alook at, it’s miles discovered that the prediction check effects of bottled consuming water sales below 20% are covered within the appropriate standards.</p>Retno Tri VulandariAndriani KusumaningrumDwi Handoko

<p>Information about the weather is needed. Weather is one of the considerations of the community in carrying out various activities. The purpose of this study is to provide information related to weather forecasts by applying Markov chain theory. The Markov chain is a random process in which all information about the future is contained in the present state. The study uses daily weather data that occurs on June 1, 2022 to June 30, 2022 to predict the weather for the next 7 days. The data used is secondary data taken from the website of the Meteorology, Climatology, and Geophysics Agency (BMKG) of Padang City. Based on the results of calculations using Markov chains, a transition matrix is obtained that is used to predict the weather for the next day.</p>Winda FransiskaRirin Hayatun NufusMohamad Syafi’iLilis Harianti Hasibuan

https://jurnal.unipasby.ac.id/index.php/buana_matematika/article/view/5451
<p>The purpose of this study was to describe the result of developing mathematics learning media using the Scratch application entitled Game Learn with Adventure on the topic of the Linear Equation in One Variable (PLSV). This study uses the Multimedia Development Life Cycle (MDLC) development model through six-stage, namely concept, design, material collecting, assembly, testing, and distribution. Furthermore, a trial of the game was conducted on the participants, namely mathematics teacher prospective students. To find out the response of participants to the media that has been designed so that researchers provide a questionnaire on Google Form and interviews. Research participants are 20 of the Mathematics Education Study Program class of 2021 semester 2 at one of the universities in Bandung. Based on the research results, it is known that the game learn with adventure on the PLSV topic can be designed very well through the Scratch application in the MDLC development model. The results of the calculation of student responses show an average percentage of 93.3% of positive statements in the very good category. Thus the need for research to determine the effectiveness of the learning process and game development on different topics.</p>Anggi LestariEyus Sudihartinih

https://jurnal.unipasby.ac.id/index.php/buana_matematika/article/view/6319
<p>This study aims to determined the effect of students' mathematical dispositions when applying the hybrid learning model to student achievement in the mathematics education undergraduate program at Wahidiyah University in the even semester of the 2021/2022 academic year. This research was a quantitative research with survey method. The sampling technique in this study used saturated sampling. The data collection method used is the documentation of the final semester exam results for student achievement data and a questionnaire for students' mathematical disposition data. In this study using a simple regression test which is calculated using the SPSS v.26 for Windows program. The research data were tested for normality, linearity, and simple regression. The regression model equation Y = 0.760 + 0.983 X + means that every 1% increase in mathematical disposition will result in an increase in mathematics learning achievement of 0.98 and vice versa. The conclusion of this study was that the mathematical disposition of students when learning Hybrid Learning affects student learning achievement positively and significantly where the influence of students' mathematical dispositions on learning Hybrid Learning on student learning achievement is 96.6% and the remaining 3.4% is influenced by other variables not examined in this research.</p>Fajar Lestari
